The Atari 600XL
Personal Computer System

Codename: Shirley (NY.) / Surely (CA.)




 The Atari 600XL home computer system.  Work began on the 600XL in the spring of 1983, just a few months after the introduction of the 1200XL computer system.  Meant to be a peer replacement for the Atari 400 computer system.  To give it a peer model number, it was half of the 1200XL model number just as the 400 was half of what the Atari 800 model number was. The 600XL came with 16K of memory, built-in BASIC and had a PBI Parallel Bus Interface on the rear of the unit to accommodate Parallel Bus expansion devices such as the Atari 1064 64K memory module and the Atari 1090XL Expansion System.    The Atari 600XL, just like the Atari 400 lacked a composite video output port. After reviewing the orignal design specifications and first revisions of the schematics of the 600XL, the long standing rumor that the 600XL was to have composite video but was cut from the design to reduce costs is in fact untrue.  The Atari 600XL looks slightly smaller then the 800XL but with the exception of the lack of composite video and 16K instead of 64K (standard on the 800XL), the Atari 600XL personal computer was functionally equivalent to the 800XL personal computer.
